|Hibiscus coccineus, Texas Star, Swamp Mallow|
Shady Gardens Nursery
Hibiscus coccineus is very easy to grow. It grows well near a pond or stream, and really enjoys a soggy spot. We have no pond, stream, or soggy spot in our garden--our Hibiscus is located in ordinary garden soil (that means dry hard clay in Georgia language). Admittedly, I do water it on occasion, but it grows bushier each year--we've had it several years now.
You can grow Hibiscus coccineus if you live anywhere in the south and as far north as USDA Zone 6!
